Using the pre-provided d3.min.js (global d3), render an interactive force-directed graph of about 40 nodes in several clusters with draggable nodes, hover highlighting of neighbors, and zoom/pan. Define the sample nodes and links inline.
thinking
Write a self-contained index.html containing a force graph of about 40 nodes divided into clusters. Include drag, hover highlighting, and zoom/pan.

Write index.html. Generate about 40 nodes inline (as literal data, but the spec says to define the sample nodes and links inline — can programmatically define clusters, but keep them as inline data. A generator function inside the script also counts as inline, but literal arrays are safer. Define clusters with names, and generate nodes/links with a seeded deterministic loop — that would still be "inline." But to be safe, write out literal data: 4 clusters of 10 nodes each, with a link array connecting them. Too much typing; a small generator with fixed cluster assignments would be fine and self-contained. Do it as a mix: literal cluster definitions, generate nodes per cluster, and links: a hub-and-spoke structure + extra links within a cluster + bridges between clusters. Deterministic (seeded RNG, or fixed pattern). That's clean enough.

If possible, verify quickly that d3.min.js exists and do a syntax check on the script portion. Also verify that the data generation is correct (e.g., the link index range). addLink(hub + i, hub + 1 + floor(rand*i)) — for i>=1, 1+floor(rand*i) is in the range 1..i, so hub+1..hub+i, but since we return if a===b, self-references are already handled by the guard. No problem. Simple sanity check on the node count / links using node? d3 is browser-only. Could also just extract the data generation logic and test it with node. Quick check:
{"command":"cd /tmp/ws && node -e \"\nlet seed=42;\nfunction rand(){seed|=0;seed=(seed+0x6D2B79F5)|0;let t=Math.imul(seed^(seed>>>15),1|seednodes: 40 links: 61 all links valid -rw-r--r--. 1 node node 8617 Aug 3 23:54 index.html

Confirmed: 40 nodes, 61 valid links. Done.
Done. `/tmp/ws/index.html` is a single self-contained file (inline `<style>` + `<script>`) that loads the local `d3.min.js` via a plain script tag — no external resources. **What it contains:** - **Sample data defined inline** — 40 nodes in 4 named clusters (Core, Analytics, Storage, Edge), each cluster generated as a hub-and-spoke structure with random chords, plus 12 bridge links between clusters (61 links total, verified valid with no self-loops or out-of-range indices). A seeded RNG keeps the data deterministic. - **Force-directed layout** — `forceLink`, `forceManyBody`, collision, and per-cluster `forceX`/`forceY` anchors arrange the clusters spatially; hub nodes are drawn larger. - **Draggable nodes** — `d3.drag` pins the node under the cursor and reheats the simulation while dragging. - **Hover highlighting** — hovering a node dims everything else, highlights the node + its neighbors and connecting edges in gold, and shows a tooltip with the node's name, cluster, and connection count. - **Zoom/pan** — `d3.zoom` on the SVG (scroll to zoom 0.25×–6×, drag background to pan), with a small help panel explaining the interactions.

EVALUATION
Interactive node-link graph visualization; drag pans and wheel zooms, but keyboard input has no effect.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
